IMPROVEMENT IN SUPPOSlTORY-MOLDS.

Specification forming part of Letters Patent No. 146,549, dated January 20, 1874; application filed December 10, 1873.

To all whom it may concern:

the following is a specification:

The invention relates to suppository-molds consisting of two parts, which are separated to remove the suppository. It consists in so constructing these two parts that they may be separated by a sliding motion in the direction of the axis of the suppository, while a lateral sliding motion or a direct separation is prevented. The object is to facilitate the removal of the suppository from the mold, and to diminish the danger of breaking it.

Figure 1 represents a full-sized perspective view of a mold constructed according to my invention, prepared to receive the melted composition; Fig. 2, the same when removing the suppositories.

The mold is metallic, and consists of two parts, A and B, held together by a rubber band, a. It will be seen that A has two tongues, which slide in grooves or slots in B. These permit the requisite longitudinal sliding motion, but prevent alllateral motion. 1) b b are the conical holes in which the suppositories are cast. They may be about one-half inch in diameter at top, and one and a half inch deep.

To use, dust the inside of A and B with lycopodium; lay them on their flat surfaces, on ice or a freezing mixture; when cold, clasp them together, as in Fig. 1; pour in the semifluid composition; and, when it has solidified, lay them on side B, as shown in Fig. 2; slide A back; this will detach the suppositories from A; then slide A forward, and the suppositories c c 0 will usually fall out.

I am aware suppository-molds have been constructed in which the two parts are hinged together at the ends, or bottom end of another form, in which pins fastened permanently into one piece fitted into holes in the other piece, thus permitting direct separation only. I claim that the suppositories are more easily removed from mine, and that the danger of breakage is less than in these forms.

Other equivalent devices may be adopted to confine the separating of A and B to a longitudinal sliding motion.

I claim- A suppository-mold composed of two parts, separable by a sliding motion in a line of the axis of the mold, whereby the danger of breaking the suppository is avoided.
